Safety precautions
AWARNING
To prevent injury or fire, take the foHowing precautions:
•When extending the ignition, battery, or ground wires, make sure to use automotivegrade wires or other wires with a 10 mm^ (AWG8) 15 mm^ (AWGIO) x 21 or more to prevent wire deterioration and damage to the wire coating.
•To prevent a short circuit, never put or leave any metallic objects (such as coins or metai tools) inside the unit.
•If the unit starts to emit smoke or strange smells, turn off the power immediately and consult your Kenwood dealer.
•Do not touch the unit during use because the surface of the unit becomes hot and may cause burns if touched.
ACAUTION
To prevent damage to the machine, take the fotiowing precautions:
•Be sure the unit is connected to a 12V DC power supply with a negative ground connection.
•Do not open the top or bottom covers of the unit.
•Do not install the unit in a spot exposed to direct sunlight or excessive heat or humidity. Also avoid places with too much dust or the possibility of water splashing.
•When replacing a fuse, only use a new one with the prescribed rating. Using a fuse with the wrong rating may cause your unit to malfunction.
•To prevent a short circuit when replacing a fuse, first disconnect the wiring harness.
NOTE
•If you experience problems during installation, consult your Kenwood dealer.
•If the unit does not seem to be working right, consult your Kenwood dealer.
Cleaning the unit
If the front panel gets dirty, turn off the power and wipe the panel with a dry silicon cloth or soft cloth.
ACAUTION
Do not wipe the panel with a hard cloth or a cloth dampened by volatile solvents such as paint thinner and alcohol. They can scratch the surface of the panel and/or cause the indicator letters to peel off.
FCC WARNING
This equipment may generate or use radio frequency energy. Changes or modifications to this equipment may cause harmful interference unless the modification's are expressly approved in the instruction manual. The user could lose the authority to operate this equipment if an unauthorized change or modification is made.

Installation procedure
Since there are large variety of settings and connections possible according to applications, read the instruction manual well to select the proper setting and connection.
1.Remove the ignition key and disconnect the negative 0 terminal of the battery to prevent short circuits.
2.Set the unit according to the intended usage.
3.Connect the input and output cables of the units.
4.Connect the speaker wires.
5.Connect the power wire, power control wire and grounding wire following this order.
6.install the unit in the car.
7.Connect the negative 0 terminal of the battery.
ACAUTION
•Be sure to turn the power off before changing the setting of any switch.
•If the fuse blows, check wires for shorts, then replace the fuse with one of the same rating.
•Check that no unconnected cables or connectors are touching the car body. Do not remove caps from unconnected cables or connectors to prevent short circuits.
•Connect the speaker wires tÿ appropriate speaker connectors separately. Sharing the negative wire of the speaker or grounding speaker wires to the metal body Of the car can cause this unit to fail.
•After installation, check that the brake lamps, winkers, and wipers work properly.

' Since the power amplifier has no parts which require operation, it can be installed at a position away from the driver's seat without any hindrances.
As generally accepted positions for its installation, places such as inside the trunk, etc. can be considered.

ACAUTION
•Do not install the unit under the carpet. Otherwise heat build-up occurs and the unit may be damaged.
•Install this unit in a location which allows heat to easily dissipate. Once installed, do not place any object on top of the unit.
•The surface temperature of the amplifier will become hot during use. Install the amplifier in a place where people, resins, and other substances that are sensitive to heat will not come into contact with it.
•This unit has cooling fans to decrease the internal temperature. Be careful not to block the cooling fan openings when installing the unit. Blocking these openings will inhibit the cooling of the internal temperature and result in malfunction.
•When nnaking a hole under a seat, inside the trunk, or somewhere else in the vehicle, check that there is nothing hazardous on the opposite side such as a gasoline tank, brake pipe, or wiring harness, and be careful not to cause scratches or other damage.
•Do not install near the dashboard, rear tray, or air bag safety parts.
•The installation to the vehicle should securely fasten the unit to a place in which it will not obstruct driving. If the unit comes off due to a shock and hits a person or safety part, it may cause injury or an accident.
•After installing the unit, check to make sure that electrical equipment such as the brake lamps, turn signal lamps and windshield wipers operate normally.

This is a 4 channel amplifier including 2 stereo amplifiers in a body. One amplifier is referred to as amplifier A and the other is amplifier B. This unit is compatible with a large variety of systems by combining the switches and functions described in the following.
^#2
#2 When INFRASONIC is set to 15Hz or 25Hz, the sound is monaural (L+R). * Note that if OPERATION is set to MONO, Lch is still monaural'.
0 Fuse (20 Ax 4)
0 Battery terminal
0 Ground terminal
0 Amplifier A speaker output terminals
0 Amplifier B speaker output terminals
^SPEAKER OUTPUT terminals
*Stereo Connections:
When you wish to use the unit as a stereo amplifier, stereo connections are used. The speakers to be connected should have an impedance of 2£2 or greater. When multiple speakers are to be connected, ensure that the combined impedance is 2Q or greater for each channel.
•Bridged Connections:
When you wish to use the unit as a highoutput monaural amplifier, bridged connections are used. (Make connections to the LEFT channel (+) and the RIGHT channel (-) SPEAKER OUTPUT terminals.)
The speakers to be connected should have an impedance of 4i2 or greater. When multiple speakers are to be connected, ensure that the combined impedance is 4£2 or greater.
ACAUnON
The rated input of the speakers should be no less than the maximum output of the
. amplifier. Otherwise malfunction may result.
® RCA cable ground lead terminal 0 Amplifier A LINE IN terminal
0 Amplifier B LINE IN terminal
0 LINE OUT terminal
These jacks output respectively the signals input to amplifiers A and B. They always output the stereo signals regardless of the position of the OPERATION switch.
®Power control terminal
®EXT.AMP,CONT (external
amplifier control) terminal
This controls the B.M.S. (See P.6).

tNPUT SELECTOR switch
This switch selects the input method of the signals to be amplified by amplifiers A and B.
•A B position:
Amplifies both of the signals input to amplifiers A and B.
*A position:
Amplifies only signal input amplifier A with both amplifiers A and B.
INPUT SENSITIVITY control
Adjust this control according to the pre-out level of the center unit connected to this amplifier.
The sensitivities of amplifiers A and B can be adjusted independently regardless of the position of the input selector switch.
NOTE
Refer to "Specifications" on the center unit's instruction manual about the pre-out level.
OPERATION switch
The amplification methods of the signals input to amplifiers A and B can be selected independently according to the setting of this switch.
•STEREO position:
The amplifier can be used as a stereo amplifier.
•MONO (Lch) position:
Amplifies the signal input from the left side only. Set to this position and make bridged connections to use as a high-power monaural amplifier. (The input right signal is not output.)
® FILTER switch
This switch allows to apply high-pass or low-pass filtering to the speaker outputs.
•HPF (High-Pass Filter) position:
The filter outputs the band of higher frequencies than the frequency "set with the HPF FREQUENCY control.
•OFF position:
The entire bandwidth is output without filtering.
•LPF (Low-Pass Filter) position:
The fitter outputs the band of lower frequencies than the frequency set with the LPF FREQUENCY control.
The speaker output is automatically turned monaural (L+R) and the bass boost function is activated.
®HPF FREQUENCY control
Sets the cutoff frequency when the FILTER switch is set to HPF.
® LPF FREQUENCY control
Sets the cutoff frequency when the FILTER switch is set to LPF.
® INFRASONIC FILTER switch
When this switch is set to 15 Hz or 25 Hz, frequencies below the setting value will be cut. This serves to get rid of unwanted vibrations that do not result in sound and, improves the speakers' ability to reproduce sound. Note that the speaker output will automatically be set for monaural (L+R) sound.
